What it is

A circulating pump supplied by Sime for use in Murelle gas boilers. It moves heating water around the primary circuit, maintaining flow through the boiler and the system. This component is listed against Murelle Advanced and Murelle PRO models.

Signs this part needs replacing

  • The pump runs but the system stays cold or heats unevenly, with radiators slow to warm.
  • Grinding, humming or rattling noise from the pump body during operation.
  • The pump body is hot but the flow pipework remains cool, indicating poor circulation.
  • The boiler locks out or reports a flow or circulation fault.
  • Water weeping from the pump housing, gasket face or pump head.

Before you order

  • Confirm your boiler model against the fitment list above before purchasing.
  • Check the part number on the existing pump or the manufacturer's parts list for your appliance.
  • Confirm the boiler's GC number matches the appliance being worked on where available.
  • If the system has lost circulation, check for sludge, air locks and seized pump valves before replacing the pump.
